JOHN F. GAIL, OF KENOSHA, WISCONSIN.

SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 646,659, dated April 3,1900.

Application filed June 16,1899.

To CLZZ whom it may concern.-

Be it known that I, JOHN F. GAIL, a citizen of the United States,residing at Kenosha,-in

the county of Kenosha and State of Wisconsin, have invented certain newand useful Improvements in Spring Bed-Bottoms, of whic the following isa specification.

My invention relates to improvements in securing tie rods in the surfaceof spiralspring bed-bottoms; and its object is to so tie the surfacecoils of the springs that lateral motion is wholly averted without themovement of the entire surface of the structure. I attain this object bythe mechanism illustrated in the accompanying drawings, in Which- Figure1 is a plan of a section of a spring bed -bottom of the classhereinbefore mentioned. Fig. 2 is a sectional edge View of the uppersurface coils of the springs and their tie-rods, and Fig. 3 shows apiece of one tie-, rod detached from the bed-bottom.

Similar letters refer to similar parts throughout the several views.

In the accompanying drawings, A represents the ordinary border-wire.

B is the upper coil of the springs, and E is the longitudinal tie-rod incommon use in the construction of this class ofbel-bottoms.

My invention consists of the-manner of securing the lateral tie-rods andtheir form and the manner of securing the links D. The tierods areconstructed with ofisets c and are placed across the bed-bottomsubstantially over the centers of the coils B, with the ofisets 0 sosituated that one will be placed between the coil B and the offset e inthe longitudinal tie-rod E, and the other will be just inside the coilof the next spring, continuing thus across the entire bottom. By thismeans I am enabled to pass the links D below the coils and the offsets eand to hook them to the tie-rods Serial No- 720,818. (No model.)

0, one end passing under the coil and engaging the rod'just inside andthe other end passing under the offset e and engaging the tierod 0between this offset and the coil of the adjacent spring. By this means Iam enabled to tie the rods so securely that it is impossible to move thecoils of the springs upon the tie-rods in either direction. The positionof these links and the manner of securing them to the tie-rods are shownin Figs. 1 and 2, in which D represents the link, and d d represent thehooked ends of the links where they pass over and are secured to thetie-rods C.

The tie-rods C and E are both secured to the border-wires A of thebed-bottom, so that no one spring can be moved laterally without movingthe entire surface of the bed-bottom. Having thus fully described myinvention, 7

what I claim as new, and desire to secure by Letters Patent of theUnited States, is-

In combination with the coils, border-wires,

and longitudinal tie-rods of a spiral-spring bed-bottom, lateraltie-rods secured to the border-wires and passing over the coils andhaving offsets for the reception of the ends of the links, offsets inthe longitudinal tie-rods and links secured at one end to an offset inthe lateral tie-rod just within the upper coil, passing thence under thecoil, and also under an olfset in the longitudinal tie-rod and upbetween this offset and the coil of theadjacent spring and tied toanother offset in the lateral tie-rod, substantially as and for thepurpose set forth.

Signed at Kenosha, Wisconsin, this 3d day of June, 1899.
